Title: Digital watermarking method wherein data bits are embedded in a digital material by addition or subtraction of a transforming matrix
Inventor: PELLY JASON CHARLES
IPC: G06T1/00
Filed: 2000-12-07
Abstract: A method of embedding data in material, which material is represented by digital samples, the method comprises the steps of: defining a matrix   D  ; selecting a block of samples having the same dimension as the matrix   D  , the values of the samples of the block forming a matrix of value C; and embedding a bit b of the data in the block by combining C and   D   to form a matrix Cs, wherein <F>Cs = C+  D  </F> represents a first value of the bit and <F>Cs = C-  D  </F> represents a second value of the bit. Further steps determine whether the embedded bit results in a valid matrix Cs. In some cases if the matrix would be invalid, a dummy bit may be embedded or matrix C may be clipped. A corresponding method of decoding comprises the steps of: determining the matrix   D  ; selecting a block the values of the samples in the block forming a matrix Cs, calculating Cs +   D   and Cs -   D  ; calculating a function <F>k=<Cs,   D  ></F>; and decoding the value of the encoded bit; wherein if k>0 then the encoded bit b has the first value and if k<0 the said bit b has the second value. Further steps check whether the bit is valid. The above steganographic ("watermarking") method is preferably applied to image data, for example acting on 8-bit image data such that a block is formed from a number of pixels and elements of the block take values in the range 0-255. The method may apply to video, audio or data material.

Title: Battery charging system
Inventor: MILLER PETER
IPC: H02J7/00
Filed: 2001-06-28
Abstract: A battery charging system (100), e.g., for automotive use, treats a battery (120), for charging, as two batteries of half the terminal voltage. The system uses transistor switches (170, 180) to allow automatic selection of "charging" or "normal" mode. This allows a device to choose its power source (main battery or backup battery) and to recharge or supply aid to an external battery whenever necessary. An alternative arrangement (FIG. 2) treats a 42V battery as three 14V batteries and avoids the need for a DC-DC converter.

Title: Systems and methods for electronic trading that provide incentives and linked auctions
Inventor: FRASER STUART A
IPC: G06Q40/00
Filed: 2000-06-14
Abstract: Systems and methods for electronic trading that provide incentives for gathering orders, making markets, and submitting block orders, and that enable linking of multiple auctions are provided. These systems and methods may first determine if the trader qualifies for an incentive. This determination may be made based upon one or more characteristics, such as price, size, duration, etc., of orders submitted to the trading system by the trader. Once the trader has been determined as being eligible for one or more incentives, the incentives that are provided may include reduced transaction costs, cash payments, priority or exclusivity in trading, self execution of transactions, etc. Similarly, before an order is eligible to be traded in an auction that is linked to another auction in the trading system, the order is preferably confirmed as qualifying to be auctioned in such a manner. Once an order is confirmed as qualifying for a linked auction, the auction is created and preferably linked to another auction based upon a characteristic of the order, such as price. In addition to being linked, information from each auction may be made available to traders in the other auctions.

Title: Image analysis
Inventor: HADDON JOHN FRANCIS
IPC: G06T7/60
Filed: 2002-12-17
Abstract: A method for the automated analysis of digital images, particularly for the purpose of assessing mitotic activity from images of histological slides for prognostication of breast cancer. The method includes the steps of identifying the locations of objects within the image which have intensity and size characteristics consistent with mitotic epithelial cell nuclei, taking the darkest 10% of those objects, deriving contours indicating their boundary shape, and smoothing and measuring the curvature around the boundaries using a Probability Density Association Filter (PDAF). The PDAF output is used to compute a measure of any concavity of the boundary - a good indicator of mitosis. Objects are finally classified as representing mitotic nuclei or not, as a function of boundary concavity and mean intensity, by use of a Fisher classifier trained on known examples. Other uses for the method could include the analysis of images of soil samples containing certain types of seeds or other particles.
